What are the things to do when producing CR2450 battery?
1. Prevent short circuit of lithium-ion battery cells
Prevent short circuit of lithium-ion battery cells
Do not place the battery cells next to conductive materials or conductive tools
Prevent the positive and negative electrodes of the battery cells from overlapping
2. Protection of positive aluminum strips of lithium-ion batteries
Since the tension of the aluminum sheet itself is 1KG, the aluminum sheet is generally not allowed to bear too much tension alone during production; when aluminum is connected to nickel, excessive welding or false welding should be prevented to prevent the aluminum strip from welding to the nickel strip and failing to reach the tension that should be borne; considering that the aluminum sheet is soft, thin, and easy to break, in order to ensure product quality, the positive aluminum strip is generally produced by back folding and inner folding processes when the aluminum sheet is connected to the nickel strip, and double-sided tape is added to protect the pole ear from external tension;
Protection of positive aluminum strips of lithium-ion batteries
3. Pay attention to the length when folding the positive and negative electrodes of lithium-ion batteries. When welding the nickel strip using the inner folding process, the length of the bent aluminum sheet or nickel strip should not exceed the length of the cell groove to prevent it from being too long and puncturing the insulating glue and the cell packaging film under pressure, thereby causing the cell to leak.
Protection of lithium-ion battery positive electrode aluminum strip
4. Lithium-ion battery cell outer packaging film protection is strictly prohibited from scratching its surface with sharp objects.
Prevent scratching lithium-ion battery cells
Finger gloves should be worn during operation to prevent scratching lithium-ion battery cells.
Prevent sharp tools such as tweezers from touching the surface of the battery cell to prevent puncturing the battery cell packaging and causing leakage.
Prevent sharp tools such as tweezers from touching the surface of the lithium-ion battery cell to prevent puncturing the battery cell packaging and causing leakage.
5. Battery cell anti-impact protection must be very careful during transportation, storage, and use. The battery cell cannot be squeezed or hit by heavy objects; when assembling the battery, it should be prevented from hitting the battery cell with force to prevent the internal diaphragm of the battery cell from rupturing and causing micro-short or even short circuit.
6. Pay attention to the cleanliness of the countertop in the lithium-ion battery cell assembly environment
Keep the work surface clean to prevent nickel strips, tin slag and other foreign objects from puncturing the battery cell.
7. The welding or tinning time of the protective tabs during the welding of the tabs of lithium-ion batteries should be as short as possible, generally within 3 seconds at 360°C.
Lithium-ion battery welding
The welding time should not be too long to avoid burning the tab glue and causing leakage. It is not advisable to wear decorative items such as rings on your hands. To avoid scratching the battery core.
8. To protect the tabs, tinning can be done before welding.
The posture of holding the battery core and tinning can easily cause short circuits. The aluminum strip and nickel strip are tinned separately.
